The Importance Of Proper Roof Ventilation

Proper Roof Ventilation Installation and what to look for if you have roof ventilation issues.

When thinking about your roof, ventilation is probably something you don’t think much about.  But the truth is that a poorly ventilated roofing system can do tremendous damage and limit the life of your roofing system and do damage to your property.  Here are some reasons to property ventilate your roofing system.   

Mold & Mildew

If your roofing system does not allow hot and humid air to escape it will stay trapped inside your attic.  This could cause mold and mildew issues, it could potentially ruin any stored items up there as well.


Softening of the Decking

Heat and Moisture can also cause early loss of shingle granules or even lead to the cracking of the shingles.


Cooling Costs

With warm air being trapped in your attic it can make it a little harder to cool your home.  This will cause your air conditioner to work harder, which will increase your utility bill.


Ice Damns

Snow can melt at the points where warm air is trapped in your roof, as the melted snow runs down the cooler portion it will freeze.  As more and more water continues to melt and freeze over it could create an “ice dam” and not allow any water to run off the roof. When an ice dam forms it could cause a backup of water and ice on your roofing system that will cause leaks. 


What Are The Signs of Having Roof Ventilation Issues

  • Increase in heating and cooling bills
  • Build ups of ice on the roof edge
  • Warped shingles or decking
  • Finding rust and corrosion on metal components


What Should You Do About An Attic That Isn’t Ventilated Properly

If you have concerns about any of the above warning signs, it’s wise to have your attic inspected by a certified roofing contractor who can inspect and verify that your roof is ventilated correctly.
